There is no standard way of getting device platform data from

a function pointer to the of_modalias_table to get such bindings

Unfortunately this approach leads to inability to make the bindings
modular.
True, but I think it's fine for now while a better mechanism is worked
out -- especially for things that are mainly used in embedded situations
where modular builds aren't as necessary.
And the solution that everybody seem to agree with (SPI driver example):

Hmm, that doesn't seem to allow for any binding mechanism other than
internal and OF, and it seems like it could be done more
straightforwardly by having the modalias point to the OF wrapper, which
then instantiates the core driver.
But the above approach has the distinct advantage of having already been
implemented. :-)
